ANDERSON METHOD or, PRODUCING FILLERS FOR RAILROAD FROGS Filed p 1928 2 Sheets-Sheet 2 Davidilflfidersoiz/ Patented Dec. 24, 1929 UNITED STATES DAVID E. ANDERSON, OF ST. PAUL, MINNESOTA METHOD OF PRODUCING FILLERS FOR RAILROAD FROG-S Application filed September 1, 1928. Serial No. 303,380.

My invention relates to the method of pro ducing rolled steel fillers by bending the fillers to suit the sections of rails with which the fillers are to be used, and then planing or cutting the fillers the desired shape to provide a sufficient shoulder under the rail which consists in the beveled point such as isused in my Patent No. 1,580,108. This method permits the manufacture of fillers in an economical manner and in some cases is to be preferred over the solid cast fillers such as areused in my patent hereinbefore mentioned.

By first bending the rolled steel filler, as will be hereinafter more fully described, and then '15 cutting the same into the desired shape, a

shoulder is provided which extends under the beveled point clear to the tip of the same and a filler can be built up from ordinary straight rolled steel fillers capable of supporting the frog point and the rail sections in a practical manner so that the fillers are capable of supporting the load and provide a strong, efficient means of filling in between the frog point and the side and guide rails. a

The objects and features of my method will be more fully hereinafter described, together with other important details of the same.

To assist in describing my method I have shown in the drawings: 7

In Figure 1 I have illustrated a plan view of my rolled steel fillers made by my method as they would appear used in conjunction with my frog point, of the type set forth in my patent hereinbefore mentioned. Figure 2 is a plan view of the two fillers used on either side of the frog point, showing the fillers bent as is accomplished in carrying out my method, and showing in dotted outtime their straight position before they are ent.

Figure 3 is a plan view of the finished fillers, only a portion of which is illustrated, after they have been bent and cut away or planed in the desired shape.

Figure 4 is a section approximately on the line 4-4 of Figure 1, in the direction of the arrow, showing the manner in which the fillers support the frog point clear down to the tip as well as the side rails.

My method consists in producing fillers for rails and frog points such as are illustrated in my patent hereinbefore mentioned in an economical manner. The cast fillers are, under present conditions, somewhat more carpensive than the fillers which are made by the method herein described and it is thus important to consider that the fillers herein set forth are desirable for certain uses in conjunction with railway rails and particularly frog points and guide rails where a more eX- pensive frog point might be prohibitive and where the wear and tear on the point is of a lesser nature than in some cases.

In carrying out my method I employ rolled steel fillers A and B, one of which is used on one side and the other on the other side of a frog point such as C. The frog point 0 herein described is of a construction of the nature which is set forth in my patent hereinbefore mentioned, having shoulders 10 on each side of the same right down to the very tip portion thereof.

The rolled steel fillers A and B are ordinarily of a straight nature from end to end and as illustrated, the straight formation on one end in dotted lines 12, such as in Figure 2. The full lines in this figure show the bending of the end 13 of the rail A to one side of the straight formation, while the rail B is illustrated with its end 14 in full lines bent out of line with the straight line formation as is illustrated by the dotted lines 12.

The first step of my method resides in the bending of the fillers A and B as indicated in the plan view in Figure 2. The dotted lines 12 show the original shape and position of the fillers before they are bent.

The fillers A and B are illustrated in cross section in Figure l. These fillers have a thick central body portion 15 and the cross sectional shape is virtually similar to an I-beam. The fillers A and B are provided with flange members 16 on either side which are adapted to fit beneath the shoulders 10 and beneath the shoulders 17 of the head 18 of the side rails19 and 20. After the rails A and B have been bent with the ofiset portions 13 and 18 respectively, as illustrated in Figure 2, the method is further carried out by planing the rail A with the recess portion 22 and also the recess portion 23. These recesses arecut into the flange 16 as illustrated in the plan view in Figure 3 of the filler A. The filler B is planned away along the web 16 at 2 so as to form the longitudinal opening 25 between the fillers A and B which is adapted to receive the upstanding web 26 of the frog point C when the fillers A and B are connected together by the bolts 27 as illustrated in Fig ure 1.

In the drawings I have illustrated the flllers A and B associated together in Figures 2 and 3 in their relative position one to the other, so that they may be more easily comprehended in their use and in the position that they assume when put together in use with the frog point C and the side rails 19 and 20.

It will be noted that by bending the rails A and B, as illustrated in Figure 2, and then planing the rails to cut away the longitudinally extending recess 22 and also the longitudinally extending recess 23 on the side of the filler A adjacent the side of the filler B which is cut away along the longitudinal portion 24, that the fillers A and B are made in the desired shape to carry out the principles of my method. The recess 25 between the fillers A and B receive the web 26 of the point C, while the recess 22 is adapted to receive the point D of the rail 28, illustrated in Figure 1.

In Figure 3 I have illustrated in dotted lines the outer portion of the fillers A and B which are planed away so that the side rails 19 and 20 can fit up against the flange members 16 of the respective fillers A and B to provide the desired positioning of the side rails 19 and 20 in relation to the frog point C. The rails 19 and 20 are beveled away at 29 and 30, respectively, to properly shape the sides of the same to form the guard rails back along the rail 28 and the rail forming the frog point C.

The fillers A and B act to provide a rigid support between the sides of the rails 19 and 20 and the frog point C which is made up of two rails with the points 0 and D inclined together. It is important that the fillers be shaped to the inside curvature of the rail which forms the frog point C such as the web portion 26 and the similar webs of the rails 19 and 20, as illustrated in Figure 4. This provides a very substantial and secure sup porting means for the shoulders 10 of the tip end of the frog C and by accomplishing this in the manner of the method set forth, I provide an economical filler, readily made up and very practical in use.

Thus the method consists in taking a pair of filler members such as A and B and bending them to divergeaway from each other at the desired angle to fit the occasion of thefitting together of the frog point and side rails,

and then planing the outside surfaces of the fillers to conform with the angle and shape of the guard and side rails 19 and 20, and cutting the inside surfaces of the respective fillers which extend adjacent each other out in a manner to receive the frog point proper and the supplemental rail point to cause the fillers to fit in close relation to the sides of the frog point, supplemental rail point and the sides of the guard rails,

In accordance with the patent statutes I have described the principles of my method and while I have set forth a particular means of carrying out the same and whileIhave only diagrammatically illustrated members which are adapted to carry out the principles and steps of my method, I desire to have it understood that variations may be made within the scope of the following claims without departing from the purpose and intent of the method set forth.

I claim:
